Hot Rod & Classic Car 20W-50 Motor Oil

Lucas Hot Rod & Classic Car Motor Oil SAE 20W-50 is manufactured with the highest quality paraffinic base oils and is fortified with a unique additive package containing high levels of zinc, molybdenum and phosphorus, which provides a tougher, thicker additive film for maximum protection even under the most severe conditions. It lowers oil temperatures, extends oil life and minimizes metal fatigue. It improves the film strength between the cylinder wall and piston rings and slows oil burning and improves pressure in worn engines. It has good cold temperature properties and stands up to high operating temperatures. It is compatible with methanol and all racing fuels, as well as with synthetic and non-synthetic oils.

Lucas Hot Rod & Classic Car Motor Oil SAE 20W-50 is for muscle, showroom, classic and trophy cars without catalytic converters. It can be used in racing applications. Not recommended for passenger car use.

Available in convenient 5 quart bottles, the formulation is perfect for the Hot Rod and Classic Car crowd with an increased zinc value of 2100 PPM. Because many of these very special machines often spend long periods (winter for example in some parts of the country) off the roads, a number of the components of the additive package used in Lucas' Marine oils to provide rust and corrosion protection have been included in its unique formula.

B Haufe uses Lucas Transmission Fix for 1989 Acura Legend

I am so excited, that I just had to write you at once. I just returned from a mobile quick lube place, for an oil and transmission fluid change.

I drive a 1989 Acura Legend. When I bought it, it had about 90,000 miles on it. I was pleased with it, except it would shift rough. I took it to a Honda dealership, and was told it probably needed "Acura transmission fluid". Since it can't be replaced all at once, we did three separate changes, at $29.00 a piece. The problem improved slightly and I let it go for about one year. Then I took it to a reputable transmission shop, prepared to have to rebuild the transmission. I was told my transmission was OK and that this model car normally shifts rough. They suggested trying a fluid change and an additive that might improve it slightly. I tried without great success.

Resolved to the fact I probably would have to drive the car as it was, I let it go until today. Sick of the rough shifting, especially into second and third gear, also it now had started to "shutter" when shifting gears. I went to Discount Auto Parts. The salesman recommended your product. I asked to have your products added to the engine and the transmission. After driving out of their driveway, I already noticed a difference. Two miles down the road I had about 20% of the rough shifting into second gear, and 10% into third.

I feel like I have a new car and can't wait to see if the engine knocking goes away (it only does it when cold).

Thank you.
